18F-FDG positron emission tomography
(PET) is used to non-invasively measure
the glucose metabolism in the brain. However PET imaging is also limited on the
longitudinal monitoring of glucose due low spatial and
anatomical resolution. This study compares the glucoCEST and 18F-FDG
PET in detecting the glucose concentration in a new traumatic brain injury
model using MRI guided pulsed focus ultrasound. Our data show that the glucoCEST could deliver comparable
results with the 18F-FDG PET results in detecting the event of hypo-metabolism in
the traumatized brain with greater higher image resolution as compared to PET scans.
